Letters Patent No. 112,825, dated March 21, 1871 pantedated March 2, 1871.

IMPROVEMENT IN HYDRANTS.

The Schedule referred to in these Letters'itent and making part of the same- Figure 3 is a vertical lateral section through a lower portion of the hydrant, and illustrates another part of the invention.

The same letters indicate like parts.

In the drawing- A represents the body of a hydrant, which pro-y jects above the ground, and may be made of iron or of other material, and is furnished withany suitable discharge-nozzle, B, iig. 1.

C is a feed-pipe, of lead or other` metal, which pipe is connected to the body A of the hydrant by means of the screw connecting-collar D.

Over the mouth of the said pipe C I place4 a rubber or other elastic ball, a, which ball, when pressed down, will stop the said pipe O.

I also provide on the body of the hydrantAa suitable handle-standard, E, to which is pivoted the' handle F.

To the said handleJ F I connect a pressing-rod, G, by a link, b, (though the link may be dispensed with.)

I also screw on the top ofthe body A a cap, D', through the top of which the pressing-rod G can work 'vertically Y v The pressing-rod Gr extends down within the body A tothe balla, as shown in figs. ,1 and 3, and is provided on its lower' end with afoot, c, which foot stands on the ball I also place within thev upper part of the bodyA a spiral 'or equivalent (rubber) spring, e, tig. l, which spring bears up against the cap D', and on a pin, x, (or equivalent shoulder,) attached to the rod G, and presses the saidmfod down, and with it its attachedfoot c, upon the ball a, and holds it rmly down in such a manner aswill prevent the water entering the body A from the, pipe C unless released from the pressure of the said rod and its foo't from the effects of the'spring e' above, which-release of pressure may be effected by pressing the handle F` down, as shown in dotted lines in tig'. 1. When the Apressure' is thus released the force of the water in the pipe O will throw up the ball a fromjt'he open end ofthe said pipe O to a height permitted by the risc of the foot c, as shown in iig. 3.

IV also make in a. side of the body A, at near the connecting-collar D, a small hole, z, which -I denominate the drain-hole, which drainfhole is intended .for the escape ofthe water' from the body A after the ball has been pressed down to the mouth of the pipe O, subsequentlyto the water being drawn through the nozzle B.

To prevent the escapevof water from the drain-holeV v z while drawing the water from the hydrant, I attachto the foot c, or to the rod G, immediately above the said'foot, a leather or other valve, s, which valve uncovers thc drain-hole z when the foot c and balla are is thrown down, asin iig. l; but' when the rod orits up, as in fig.. 3, the said valve covers `the said drainhole 'z and prevents any escape of water from the body A.

To dispensewithtne necessity of holding the handle F down when-watei` is to be drawn for a length of time, I attach. to the handle-standard E: (or to an equivalent place at the top of the body A) a swingf ing link or tie, H, figs. l and 2, by any suitable pivot which will enable it to be swung as shown in dotted lines in iig. 1, I

I also make into the upper edge of the .handle F several slight notches, n fv, which notches, or one of them, will receive and holden the cross end ofthe link H when the handle is thrown down; and thus the said link willbe made to hold down the said handle F, andpresent a ow'of water that may be de' sii-ed, without the'continual 'personal presence and ex ertion of the person who Aoperates this hydrant to draw water. A hook might be substituted for the said link, or the link could be pivoted to the handle and held, by one of a series of notches, on the side ofthe hydrant, to eect the same results.

By this invention a hydrant could be constructed which would not be `liable to get out of order very readily, and would prevent the freezing of water in the winter,and, also, would not require the personal presence of a person when drawing water for a length of time. l

.Having thus described my invention,

W hat `I claim, and desire to secure by Letters Patent, is-

'lhe combination of the notched lever F and the stop-link H with the valve a and its rod G, and the springe, which closes said valve in 'opposition to the pressure of thewater in the main, substantially as and for the purpose set forth.
